SAMUEL MARSOHIK, OF BRIINN, AUSTRIA-HUNGARY.

DEVICE FOR PREVENTION OF ARBITBARY REGISTRATION IN COUNTERS FORMECHANICAL LOOMS.

To all whom it may concern:

Be it known that I, SAMUEL NTARSOI-IIK, a subject of theAustro-I-Iungarian Emperor, and resident of Schmerlingstrasse 37 a,Briinn, Austria-Hungary, have invented certain new and usefulImprovements in Devices for Prevention of Arbitrary Registration inCounters for Mechanical Looms, of which the following is aspecification.

My invention relates to improvements connected with counters formechanical looms.

The counting devices used in mechanical looms (weft-counters orregisters) are in consequence of their arrangement affected with theshortcoming of being readily shifted by workingn'ien, 2'. 6. withoutsetting the loom in motion. As frequent altercations regarding thepayment of wages have been thereby caused calling into question thereliability of such apparatuses, these counters should meet thefollowing conditions in order to be perfectly reliable: 1/. In theregular weaving process the counter must register or add onward, 2/. Inweaving backward (taking back, seeking of wefts or removal of same) theymust register backward or subtract, 3/. In changing the pattern card byhand when the loom is not running they must remain inactive.

The method applied at present for setting the pattern-cylinder in motiondoes not meet these requirements, since the latter either forms onepiece with the cylinder-spindle or is solidly fixed thereto. Furthermorethe moving of the cylinder takes place by the well known turning-hooks,which may be readily adjusted by the laborer so that the turning of thepattern-cylinder and thereby also the further registration of thecounter by hand is made possible. The cylinder spindle is even generallyprovided for this purpose with a hand-wheel, whereby the arbitraryshifting of the counter by workingmen is indeed favored.

In the present invention the above conditions are duly complied withowing to the fact of the pattern cylinder sitting loosely on thecylinder-spindle and being oinable to same by means of a clutchcoupling. The cylinder-spindle with which the counter is fixedlyconnected, is furthermore turned from the main shaft of the loom bychainwheel transmission and a reversing gear (preferably by a pinandstar-Wheel gear) so that a turning of the cylinder axis andSpecification of Letters Patent.

the counter connected therewith cannot be done by hand, the moving ofthe patterncylinder being possible however after disengaging thecoupling, whereby the cylinder axis and the counter remain in a fixedposition. The star-wheel of the above gear is turned by twodisengageable pin-wheels meshing from the opposite side and revolving incontrary directions, whereby the for ward and backwardanotion orrespectively adding and subtracting of the counter becomes possibleduring the running of the loom.

In the accompanying drawings: Figure 1 shows a side view of the devicein connection 'with a pattern cylinder for pattern chains consisting ofrollers or a vertical section respectively according to line A-A of Fig.2. Fig. 2 presents a horizontal section according to line BB of Fig. 1.Fig. 3 shows the same arrangement for a pattern cylinder with pasteboardcards and rocking cylinder-batten, also in side view and verti calsection respectively.

As is evident from Fig. 2, 1 represents the cylinder-spindle upon whichthe pattern eylinder 2 with the little chain-wheels 3, 3 sits loose thesaid cylinder-spindle also operating the counter 26 of any desiredconstruction.

The pattern cylinder 2 is fitted with the coupling or clutch member land a ratchet 5 which can be operated by a hand lever, not shown, so asto cause the pattern cylinder to turn one surface at a time, thecoupling or clutch member being so disposed as to be always ready toengage. The second coupling or clutch member 6 is shiftably arranged bymeans of groove and feather on the enlarged part 1 of the cylinderspindle 1 and can be moved by the hand lever 7, which is turnable aroundthe pivot 10 fixed to the bearing 8, such hand lever being automaticallykept in action by a spring 11. The cylinder spindle 1 resting in the twobearings 12, 12 of the frame of the loom, is

impelled by the star-wheel 13 which pos-' sesses just as many radialslits as the cylinder 2 has surfaces. Into the star-wheel 13 twoshiftable pin-wheels 14 and 15 engage, which by means of feather andgroove are axially shiftable on the extended hubs 16 of The two toothedwheels 17 and 18 run loose on the bolts 19 and 20 fastened in thebearings 8 and 9, such toothed wheels being impelled by the chain wheel21 fixedly joined to the toothed wheel 17 and by the chain 22 from themain shaft or from another place of impulsion of the loom. The two pinwheels let and 15 are shiftable through the operation of the three-armedlever 23 by means of a cord or strap 21 from the weavers stand, saidlever being held by a spring 25 in the position for ordinary weaving, asshown in Fig. 2. The efl ect of this mode of operation is as follows:During the forward weaving process the pin wheel let is engaged withstar wheel 13 the former being constantly maintained in this position bythe sprin 25. The turning of the cylinder 2 in the direction of thearrow I thereby produces the forward movement of the counter, while thepin wheel 15 being pushed back is not engaged with the star wheel 13(Fig. 2). By pulling the cord 24 the pin wheel 14 will become disengagedwhile the pin wheel 15 becomes engaged and, while thus producing theopposite turning direction, the reverse movement in the direction of thearrow TI is effected, corresponding to the backward motion, 2'. e. forthe taking back of the cards or the seeking and removal of wefts. One ofthe two pin wheels 14 and 15 being constantly engaged with the starwheel 13, the cylinder spindle 1 and consequently the counter 26impelled by the same, become barred in case of the loom standing still,allowing no turning of the cylinder spindle 1 by the operator.

The turning of the pattern cylinder 2 by hand ensues after disengagingthe coupling half (3, by means of the disengaging lever 7, quiteindependent from the cylinder spindle, which is therefore not influencedby the turning of the pattern cylinder. The coupling or clutch members4, 6 and the ratchet device 5 having as many divisions as the patterncylinder, the two coupling halves -t and (3 always stand in an engagingposition opposite to each other being automatically engaged by thespring 11 after releasing the disengaging lever 7 so that it cannothappen that in starting the loom the pattern-cylinder will remaindisengaged. In order to prevent an axial shifting of thepattern-cylinder when the coupling half or clutch member (3 is shifted,the cylinder-spindle 1 has a larger diameter at that place where thecoup ling half or clutch member 6 is arranged.

Through the two toothed wheels 17 and 18 becoming engaged in front ofthe starwheel 13, the latter is covered up thus being inaccessible tothe operator.

The complete casing may be accomplished in the well known manner bymeans of a protection cover inclosing the engaging position of the twotoothed wheels 17 and 18 and also preventing accidents.

Fig. 3 shows the application of this device on a pattern cylinder withrocking cylinder batten. In this arrangement the actu ating device ismounted on the spindle 27 serving as turning axis for the cylinderbatten 28. On the spindle 27 a chain wheel. 30 is fastened, which by achain 31 is geared to the chain wheel 32 fixed to the cylinder spindle29, thus causing the turning movement of the spindle 27 to betransferred to said chain wheel 32. The connecting rod pivot allyconnected with the cylinder batten 28 is represented by 33 causing therocking motion of said cylinder batten 28. On the spindle 29 the patterncylinder 34 is loosely arranged, which may be coupled with same in themanner above described by means of the hand-lever 7. The impulsion ofthe star wheel 13 also takes place in the above manner through pinwheels 1st and 15, toothed wheels 17 and 18, chain-wheel 21 with chainfrom any rotating portion of the loom.
